LOCOIVIOTIVE-ENGINE FOR PRODUCING INCREASED ADHESION TO THE RAILS WHEN REQUIRED.

Specification of Letters Patent No. 19,000, dated December 29', 185'?.

To all whom it may concern:

Be it known that I, FRANCIS TINDi-IAU- snn, (civil engineer,) of Duderstadt, in the Kingdom of Hanover, have invented certain new and useful Improvements in Locomotive-Engines Thereby the Adhesion is Increased on Tet or Slippery Rails; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which-- Figure l, is a vertical section through the smoke pipe and smokeboX of a locomotive engine whereto my arrangement for drying rails before the passage of said locomotive and for increasing the adherence of locomotive-wheels to the rails, is applied. Fig. 2, is a side elevation of the smokeboX and smoke pipe. Fig. 3, a top view of a horizontal section above the smokebox. Fig. 4, is a hori- Zontal section through the chimney or smokepipe, lastly, Figs. 5 and 6 are sectional views on a larger scale of an arrangement for lubricating parts in friction.

The nature of my invention consists in providing the smokepipe of locomotive engines with a fan blower, which is put in rapid motion by the escape of steam, which blows the smoke down on the rails in advance of the front wheels through pipes, the lower opening of which is within two inches from the upper surface of the rails.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation.

My apparatus is placed in a space between the smokebox and the smokepipe of a locomotive engine and is independent from all other parts of the engine.

R R represents the smokeboX with an opening 0 0 at the top. On the top of the smokebox is secured an elliptical envelop B of a larger diameter than that of the smokepipe D which is united thereto by means of a conically or otherwise shaped envelop D D. It is advantageous to secure the latter to the envelop B by means of bolts rather than byrivets, as it would be very ditlicult to adjust the parts placed inside without that precaution.

The envelop B is of an elliptical form as seen in Fig. 3, showing at the inside and fastened to both the smoke boX and the envelop B, partitions B B extending in a circle from the ends of the smaller diameter of said envelop more than half way toward the other side. On each side of B, B, there is a circular hole through which the smoke will be forced down the pipes C C. These pipes descend on each side of the'smoke box. so that their lower orifice faces the rails as near as practicable.

The end of each pipe is flattened in such a manner that the opening be a rectangle of the width of the rail and consequently of a length equal to three times the radius of the pipe. This opening being turned lengthwise, all the smoke escaping through it will come in contact with the rails. In each pipe is a register valve E which is connected by cranks and links with the rock shaft H. This is moved by a hand lever F which is wit-hin the reach of the engineer.

The exhaust pipes R R are united in one by a connection R2 R2 cast in one piece, which is bolted to them. The lower part of this casting forms a journal with a set screw for receiving a pivot. The upper part R3 R3 is turned as shown in Fig. l to form a seat or guide to the revolving fanshaft A. A. Four arms F2 F2 are riveted against the smokepipe, they are cast of one piece having at the converging point a collar for the reception of the upper end of a vertical shaft. This collar is provided with a brass box and a set screw F, disposed in the usual way. Above the collar a rocking shaft M passes through the smokepipes in journals fastened to it; this shaft projects out both ways and carries two parallel projecting arms inside the chimney and two others outside in a nearly opposite direction with that of the two first. From the arm E3, E3 hang by means of links a cylinder E2 E2 of such a diameter that it may slide easily up and down inside of the smokepipe. This cylinder acts as a valve. Then let down as represented in Fig. 1, z'. e., when it rests on the plate A4 A4, it closes the passage from the smoke box or from the space between the envelop B B and the partitions B B, to the smokepipe; when raised it opens that passage. The rockshaft M is connected with another rockshaft H in such a manner, that when the valves F F are open, the valve E2 E2 is closed and vice versa.

I have now described all the stationary parts together' with those that have only a rocking motion and which are never taken out. I will now proceed to describe the main part ico of my invention which consists in the construction, arrangement, and operation of the following parts viz, the shaft A, pipe A A, fans A3 A3 and appendages, all being carried by the central shaft A'and adjusted thereto before placing it in its journal.

A A is a' cast iron pipe both ends of which are open. This pipe carries by means of arms the two collars a and a, the one at the top the other at the bottom. Tothese collars is keyed the pipe A A and near to its upper end project two pipes A2 A2, shown in Figs. 1 and 4. These are of a smaller diameter and bent so as to form an angle of 450 (degrees) with both the horizontal and vertical planes passing through the axis of the shaft A. The pipe A A is surrounded by a horizont-al circular disk A2 A4 of plate-iron and by four fans A3 A2, which are securely iiXed by means of screws or bolts to both the pipe and the disk. The lower end ofthe pipe A A is turned to fit loosely into the upper end R3 R3 of the connection piece R2, while its top forms a sort of box containing the collar a; care is taken in so shaping the arms around the collar a, that their upper face be symmetrical in shape being equal in size and leaving equal spaces between them. This is mounted by a fiat disk e somewhat larger than the inside diameter of the pipe and into which corresponding and similar openings to those just now described are cut, as well as a central hole for the passage of the shaft. A notch is made in the edge of this disk and a stopbolt attached to the iange of the pipe plays into it to limit the motion of the disk in such a manner that when it is turned one way the openings in the disk will correspond to those in the pipe whereby an outlet may be established and that when turned the other way the pipe be closed. A spiral spring g one end of which is hooked to the shaft while the other is attached to the disk has a tendency to keep the top of the pipe A A closed. The'disk is also connected with the pipes by means of two toggle joints Z2 and c3 of which e and c and e2 and c2 are the 2 links. The ends g and 7i of these links are secured respectively to the pipe and to the disk.

7L works around a pin fast on the iange of the pipe A A while the other end g works around a pin fast on the disk. It is obvious that when the oints c2' or Z3 or both of them are pulled away from the center, the pin in p being stationary, a motion will be imparted to the pins in g in the direction of the toggle joints, causing the disk to rotate around its center whereby the pipes A A will be opened.

The operation of my whole apparatus is as follows: The valves E, E, being opened and the valves E2 E2 closed, while the locomotive is running the exhaust steam jets pass through the pipes R R and A A and escape in the chimney through the tubes A2 A2. The reaction on the pipe A A arising from the inclined position of said tubes actuates its rotation with great rapidity carrying along the fans A3 A3. The smoke, carbonio acid and other gases resulting from the combustion of the fuel and which fill the smoke boX are brought up by suction through the opening o, between the fans and are thrown byv centrifugal force between the envelop B and the partition B, whence they are forced through pipes C C and projected against-the upper face of the rails which they render apparently dry instantaneously. Vhen the whole of the smoke is not necessary to dry the rails, the engineer pushes forward the hand lever E4, thus partially closing the pipes C C and partially opening the regulating valve E2 E2. Then the register valves E E are entirely closed and the regulator entirely open all the smoke escapes through the chimney. In this case there is less resistance against the fans they doingl less work, and as a consequence they acquire an accelerated motion, the motive power being the same.

The object of the disk covering the top of the pipe A A is to counteract this effect. As soon as the motion of the pipe acquires a certain degree of velocity the joints e3 Z3 made heavy on purpose are driven away from the center by the centrifugal force; this motion as alreadydescribed causes the top of the pipe to open, the steam inside rushes out through the openings and the escape through the tubes A2 A2 is thus lessened, and the velocity decreased in proportion.

Claims.-

1. In combination with the exhaust steam pipes of locomotive engines I claim the apparatus'herein described for drawing from the smokeboX and forcing upon the rails in front of the driving wheels, the products of combustion when said apparatus is revolved to operate by the reaction due to the escape of steam from the cylinder substantially as set forth.

2. I also claim the arrangement herein described for regulating the supply of hot air, smoke and other products of combustion upon the rails, by causing the draft, either through the chimney I), or the pipes E, or

both the chimney and the pipes, substan- Y F. WINDHAUSER.
